Abstract (en)
[origin: WO2014037652A2] The invention relates to a speed-reducing unit (1) having an epicyclic gear train, in particular for a turbine engine, comprising an inner planetary gear (2) and an outer planetary gear (3) which are coaxial, the inner planetary gear (2) being rotatable about the axis (X) thereof, the outer planetary gear (3) being stationary, at least one planetary wheel (4) rotatably mounted on a planetary wheel carrier (6) and engaging with both the inner planetary gear (2) and the outer planetary gear (3), the planetary wheel carrier (6) pivoting about the axis (X) of the inner planetary gear (2) and of the outer planetary gear (3), the planetary wheel (4) comprising an inner cylindrical surface pivotably mounted about a cylindrical surface of the planetary wheel carrier (6). The speed-reducing unit (1) further comprises an improved means for supplying oil at the interface between said cylindrical surfaces.
